PDQ VAULT and High Security Keys and Key Cuts
These are PDQ factory keys for two closed key systems: the VAULT patented keying system and PDQ high security cylinders and cores. The range covers the VAULT key blank and VAULT master, grand master, great grand master, control and change key cuts, plus high security cut keys for 6-pin cylinders, 7-pin SFIC cores and 6-pin LFIC control keys on the TA keyway.
Key Features
- VAULT keys are tapered to pass the patented VAULT door inside the core, which blocks standard keys
- VAULT is covered by U.S. Patent #12338653 through 2044, and unauthorized duplication of VAULT keys is prohibited
- VAULT keys also operate standard SFIC cores, so a facility can move to VAULT in phases
- High security keys are cut at the factory; blanks for high security cylinders are not sold
- Key cuts cover every level of a master key system, from change key up to great grand master
Technical Specifications
- Manufacturer Part Number: I02400
Frequently Asked Questions
What is a restricted or patented keyway?
A restricted keyway uses key blanks set aside for limited use, so keys and cylinders can only be ordered with authorization. A patented keyway adds legal protection: PDQ VAULT is covered by U.S. Patent #12338653 through 2044, and only authorized distributors can supply VAULT keys and cores.
How does a master key system work?
A master key system groups locks so one key opens many doors while each door keeps its own change key. Levels run from change key to master, grand master and great grand master keys, and PDQ recommends no more than four levels.

PDQ I02400 – Frequently Asked Questions
1) What exactly am I ordering with PDQ I02400 - a key blank or a cut key?
I02400 is a grand master key cut (GMKC) on the PDQ VAULT patented keying system, so it ships cut to your system's grand master combination rather than as an uncut blank. If you need an uncut VAULT blank to cut yourself, that is a separate item; VAULT blanks exist, but blanks for PDQ high security cylinders are not sold at all, since those keys are cut at the factory.
2) Will a PDQ VAULT grand master key open my existing standard SFIC cores?
It will. VAULT keys operate standard SFIC cores as well as VAULT cores, which is what lets a facility convert to VAULT in phases instead of changing every core in one shutdown. The reverse is not true: the patented VAULT door inside a VAULT core blocks standard keys, so an old master key will not pass a core you have already swapped.
3) Can I get PDQ VAULT keys copied at a hardware store or locksmith?
No. VAULT is a closed, patented system covered by U.S. Patent #12338653 through 2044, and unauthorized duplication is prohibited. Keys and cores come only through authorized distributors with proper authorization on file, which is the point of the system for a property manager or facility that cannot afford stray copies.
4) Where does a grand master key sit in a PDQ master key system?
A grand master sits one level above the master keys: change keys open single doors, a master opens a group, a grand master opens multiple master-keyed groups, and a great grand master sits above that. PDQ recommends keeping a system to no more than four levels total, so a grand master is usually the right choice for a building or campus wing that already has several master-keyed departments under it.
5) What do I have to supply so PDQ can cut the right grand master key?
Because this is a factory cut to your specific system, the key has to be tied to an existing or new VAULT keying record: the system ID and the grand master level you want it cut to. PDQ publishes its keying systems and order forms so the authorization and keying schedule can be submitted with the order (https://zensupply.com/content/pdf/pdq/pdq-keying-systems-and-forms.pdf).
6) What is the difference between PDQ VAULT keys and PDQ high security keys on the TA keyway?
Two separate closed systems. VAULT is the patented system with a tapered key that passes a door inside the core, and it also runs standard SFIC cores. The PDQ high security line is a different program: factory cut keys for 6-pin cylinders, 7-pin SFIC cores, and 6-pin LFIC control keys on the TA keyway. A VAULT grand master cut like I02400 belongs to the VAULT system and is not a TA keyway key.
7) Is this VAULT key for commercial door hardware or residential locks?
It's a commercial door hardware item. VAULT keying is built for facilities running master key systems across many openings, which is why the levels run up to great grand master and the keyway is restricted. A single-family residential job has no use for a grand master cut.
